Its relative speed to the Earth now is about 21 kilometers per second, that is, 1.8 million kilometers per day. Relative to mars, the probe is flying about 200,000 kilometers per day towards Mars. The probe is flying faster and faster as it gets out of the influence of heliocentric gravity. At present, the speed is basically stable at around 22 kilometers (per second) (relative to the Earth)."

Storyline


China's Mars probe Tianwen-1 had traveled more than 400 million kilometers by 06:00 Sunday and is expected to enter Mars orbit next month, according to the China National Space Administration (CNSA).

When the Tianwen-1 probe arrives near Mars, it will be about 190 million kilometers away from the Earth with the total flight mileage reaching 470 million kilometers, CNSA said.

China launched the Mars probe Tianwen-1, which means quest for heavenly truth, on July 23, kicking off the country's independent planetary exploration mission.

The probe has flown in space for 163 days and is currently around 130 million kilometers from the Earth and around 8.3 million kilometers from Mars.

The spacecraft, consisting of an orbiter, a lander, and a rover, is expected to reach the red planet's orbit in around February 2021. The expected touchdown time is May 2021, about three months after Tianwen-1 arrives in the Mars orbit.

At present, the orbiter has completed the third on-orbit self-check, and all systems are working normally.

Li Zhencai, deputy commander of the Tianwen-1 Mars probe project of China Academy of Space Technology, explained the flight path, speed and mileage of the probe.

While the probe is chasing after Mars in space, Mars and Earth are moving around the sun simultaneously, and the distance the probe actually travels is farther than its straight-line distance to the Earth, he said.

"The probe is currently flying at a speed of about 23 kilometers per second, which is basically two million kilometers per day. Its relative speed to the Earth now is about 21 kilometers per second, that is, 1.8 million kilometers per day. Relative to mars, the probe is flying about 200,000 kilometers per day towards Mars. The probe is flying faster and faster as it gets out of the influence of heliocentric gravity. At present, the speed is basically stable at around 22 kilometers (per second) (relative to the Earth)," said Li.

The distance between Mars and Earth changes periodically, with the nearest 50 million kilometers and the farthest reaching more than 400 million kilometers.
